Question

7added to thrice a number gives 25by3.find the number​

Answer 1

Step-by-step explanation:

Let the number be = x

Thrice of that given number = 3x

When it is added by seven then = 3x - 7

We know that when 7 is added to thrice of the given number gives $\frac{25}{3}$

∴ By the problem,

=> 3x - 7  =    $\frac{25}{3}$

=> 3(3x - 7)  =  1 (25)            [Cross multiplication]

=> 9x - 21 = 25

=> 9x = 25+ 21

         = 46

=> x  =  $\frac{46}{9}$

Hence, the required number is $\frac{46}{9}$ (Ans)
